Figures 2, 4) availability is maintained by de novo synthesis from precursor amino acids, (glutamate, cysteine, and glycine), reduction of GSSG by glutathione reductase (GR), and uptake from exogenous GSH sources across plasma membranes (Figure 4) (62, 63)
Avoid mixing copper peptides with strong, lowpH actives like highstrength vitamin C (ascorbic acid), aggressive AHAs/BHAs (glycolic, lactic, salicylic acid), and potent retinoids in the same step, as they can destabilize peptides or increase irritation
liposomal forms offer superior absorption
